The present invention relates to a portable battery and a charger mechanism that can be used for charging a mobile phone.

Advances in electronic technology have diversified the functions of mobile phones into a wide range of areas.

In particular, as mobile phones have evolved into smartphones, they have gone beyond traditional voice calls and text communication tools, and have evolved into innovative tools that can use various contents through wireless Internet access as well as functions such as digital cameras and MP3 players. . As a result, the usage time of the mobile phone has been greatly increased, but the development of power storage technology that must accompany the usage rate of the mobile phone is relatively very slow. Several methods have been proposed to compensate for this reality.

First, it may be considered to increase the storage capacity by expanding the size of the battery. However, when the size of the battery is expanded, the overall size of the mobile phone is inevitably expanded, so the portability becomes very inconvenient, and the capacity of the battery is still limited because of its limitation.

Second, you can carry extra spare batteries. In this case, it is cumbersome to replace the battery, and there is a failure in continuous use or continuous communication of the used content. In addition, since the spare battery is also limited in capacity, it is often unsatisfactory for some users. Furthermore, depending on the type of mobile phone, there is no choice depending on the type of mobile phone, as some manufacturers of the mobile phone may not be able to replace the battery.

Third, it is possible to carry a portable large-capacity battery as in the Republic of Korea Utility Model Registration No. 20-0310501 (hereinafter referred to as 'prior art 1'). In general, portable high-capacity batteries have a storage capacity that can be used to charge a battery that is connected to a mobile phone more than three times. The method of carrying a large capacity battery is more convenient than the first and second methods above. In addition, the portable large capacity battery has a universal utility that can be used even when the battery replacement is impossible. The present invention relates to such a portable large capacity battery.

A large capacity battery, such as the prior art 1, is currently electrically connected to a mobile phone via a cable. This causes the inconvenience of the user having to carry the cable together and the hassle of using the cable between the mobile phone and the portable large capacity battery. There is also a risk of the user losing the cable. Furthermore, when using a mobile phone while connected to a portable high capacity battery by cable, it is inconvenient to use because the portable high capacity battery must be held and the mobile phone must also be held.

On the other hand, the battery coupled to the recent mobile phone can be stored by being connected to the power supply via a cable in the state coupled to the mobile phone or connected to the power supply in a state that is already held in a separate charger port connected to the power supply through the cable. Can be. This connection to the power supply via a cable or a separate charger port may be simple, but depending on the user may be a cumbersome task.
